9.50mL of .100M NaOH + 8.00mL of .100M of HC2H3O2. Find the pH.
Okey this is what I did. 8.00-9.50=1.5mL or .0015L .0015L x .1000

Never mind I figured it out. I was forgetting to make the reaction 100% to the reactant side and then working it out from there.
THANKS DR.BOB
Soo...what am I doing wrong? Sorry I'm a bit confused here. pH= 4.75 + log (.06040/.02079) ? Then I get 5.203 which isn't the right answer either.
HI again Dr.Bob This is what I'm doing .10M (.0122L)= .00122 moles of NaOH .00122/(.008+.0122)= .06039M .10M (.008)= .0008 moles CH3COOH .0008-.00122=.00042 moles HCl unreacted .00042/(.008+.0122)=.020792M CH3COOH pH= pka + log (x/y) pH= 4.75 + log
Oh yes it is a typo my bad. But you got the right answer though. Thank you and thank you for the short cut on the calculator too, I was doing it just like you did it but my the calculator was having overflow problem
Never mind I got it. I was just not seeing the PV=nRT relationship here lol. Thanks anyways.
Thanks Dr.Bob
I got C). 33.75 or 33.8. Use Spectrometry. You have 45.0ml of NO2 right. Convert that to Liters so you get .045L. Since its at STP convert .045L to moles using 22.4 L/mol. (.002 moles of NO2)[(6 moles of NH3)/(8 moles of NO2)] = .0015 mole of NH3 use 22.4
Wait never mind I figured it out. 1/F = F so 1/102 right?
Thanks drbob, I was just getting confused by the direction of the equilibrium. how can you tell which way the equilibrium shifts?
